' new and useful Improvements in Roofing- Tiles and Fastening Means Therefor, of

which the following is a specification. 7

The subjectmatter of this' invention isa roofing tile of the type which is usually com posed of reinforced concrete, Portland cement or the like and is made of sufiicient size and otherwise adapted to be placed'directly upon a'ndfastenedto the purlins.

Thefprimary object of my invention is to I produce a tile having fastening means secured to and cooperating with the under side vof the overlapping portion of a tile to providea socketed seat, open at its rear end, and adapted to receive and form a joint withthe underlying portion of an adjacent tile and also to engage the purlin and fasten the tiles thereto. f v

Another feature of my invention comprises the provisionat opposite ends of each tile "of cooperating, fastening and ahning means of novel form whereby the ends of adjacent tiles may be interlocked and allned with each other andsimultaneously fastened to the purlins. v

Another feature of my. invention comprises the provision of a plurality of "nuts embedded in the bottom surface of the overlapping portion of the tile and means co-' operatingtherewith and preferably comprising a Z-shaped clip, for engaging the end of the adjacent tile and fastening" both ends to the purlin. V v v V I Other objects will be in part obvl ous from the annexed drawing and inipart lndicated I in connection therewith byzthe following analysis of this invention.

' This invention accordlngly also consists in the features of construction combinations of parts and in the unique relationships of, members and in'the relative proportioning and disposition thereof, all as more ,completely outlined herein and in the said drawin s. i

%o enable others skilled in the art' so fully to comprehend the underlying features 1918, Sea No. 230,241.

of this invention they embody the same, by. numerous modifications in structure and" relation contemplated thereby, drawings depicting. preferred forms have been annexed as a partof this disclosure and in the drawings like characters of reference Specification of Letters Patent;

denote corresponding parts throughout all the yiews of which-- 7 V Flgure 1, is a plan view of a plurality of tiles fastened together as employed in roof- Fig. 2, is a longitudinal: section through tilesembodying my inventionshowing the same fastened to the'purlins,

' Referring now to Figs. 1 to l6 :of these to it beneath its overlapping marginal portion 2, one or more fasteningvdevices 4, which cooperate with the under face 'of the said overlap to. form a socketed seat, preferably open at its rear end, for the reception of the underlying marginal portion 3 of an adjacent tile. 7 The fastening device 14, as shown, comprises a clip Z-shaped in conformation and is secured to the under face of the marginal overlap or contiguous portion by means of'a nut '5,"embedded in the cement'itious material from which" the tile is formed; The nut 5 extends only to the under-surface of the tile so as to'leave the "drawings, each of the tiles 1, has secured V upper "face thereof free from holes, which would prevent the formation of a tight'joint,

and meshes witha'screw' 6, which as shown is passed through'a hole 7 in a flange '8,-

for the reception of the underlying portion of an adjacent tile. llhis flange 10 preferably has a downward inclination with respect to said under face of the overlap so as to permit a resilient engagement between it and the under face of the said underlying portion of the adjacent tile and the flange 11 of a purlin 1-1, to which the tiles are secured. V

Each tile has an underlying marginal portion 3, which is preferably provided with notches 12 in vertical alinement with the fastening devices 1. These notches are adapted tobe engagedby and interlocked with the fastening devices a, the intermediate portions 9, of the two fastening devices 1' entering the notches 12, while the flange 1O bears against the under face of the underlying portion and the inclination of'the flange 10 permits it to take under the flange of the purlin so as to secure the tiles thereto.

A kerf 13 is formed transversely along the under face of the overlapping portion of the tile and this kerf is filled with plastic cement or the like, to assist in the formation of a water tight joint.

The tiles may be laid substantially in the conventional manner, 2'. e. the bottom row first and the next row having the clips secured thereto will be slid over the top edge of the said bottom row so that the intermediate portions of the fastening devices or clips will enter the notches and the free flange portion will bear against the under surface of the underlying portion of the first row and furthermore will engage beneath the flange of the purlin. I

In the modified form of device shown in Fig. 7, instead of providing a Z-shaped clip,

the shank 1d of a bolt 15, enters and interlooks with the notches 12, while a plate 16 has a hole 17, through which the bolt extends and said plate bears against the under face of the underlying 111L1""1I1?tl1)01'l31011 and engages beneath the flange of the purlin.

In laying tile, having fastening devicesof the character last above described, it is desirable to have a man stationed below the purlins for the purpose of interlocking the bolts 'with the notches and screwing the same home to cause the plates 16 to bear against the under face of the tiles and the flange of the purlins.

The tiles 1, are also preferably provided with. the usual longitudinally-disposed rib 18 at one edge, a roll 18 cooperating with the ribof an adjacent tile, and with an intermediate roll 19, or the like, for the purpose of embracing the cooperating ribs and rolls at the overlapping portions thereof.

Plastic cement or like material may be inserted between the rolls and ribs to assist in forming a tight joint.
